Note: “--“ represents the measured noise monitoring data lower than the established notional background level/discarded under strong wind.

 

b. MANUAL NOISE MONITORING DATA

 

The hoarding works for the construction of transmission system at Pak Kok Tsui were completed on 11/5/2002.  The civil works would tentatively commence in June 2004.  As there would be no construction work during the period from 12/5/2002 to June 2004, the manual noise monitoring at Pak Kok Tsui would temporarily be suspended within this period.
